Tube 4,5

Selecting the right size starts with the diameter of the wire or cable you want to insulate. This range offers several inner diameters, including 3, 4, 5, and 6 mm, plus lengths around 20 cm. A shrink ratio of 2:1 means the tube will reduce to about half its supplied diameter, giving you flexibility across various wire gauges. Materials are polyolefin, and the outer jacket is flame retardant to enhance safety during use.

Polyolefin heat shrink tubes are durable insulators that provide reliable protection for wires and cables. They shrink tightly to form a seal, with a continuous operating temperature range from 55°C to 125°C and a shrink temperature around 120°C, while the outer layer offers flame retardancy and moisture resistance to safeguard connections in practical projects.

A 4 mm inner-diameter tube set at 5 meters in length, in black, is a versatile choice for common computer, mobile, and charger wiring repairs. This option provides a durable insulation layer, a clear shrink temperature target, and a practical length for multiple cables, making it suitable for routine household fixes and light electronics work.

Yes. Some sets include multiple colors and multiple sizes, offering 8 or more sizes with several colors in a single package. For example, a complete kit can provide a range of inner diameters and colors so you can match your project precisely while keeping everything organized in one purchase.

Most heat shrink tube sets come with a one-year warranty, reflecting confidence in their durability and performance. This coverage supports ongoing use across various home and workshop tasks, from simple repairs to more involved installations.

For broad use around the home, a mixed-size set covering 3–6 mm is highly versatile and suits many common cables. If you frequently repair larger harnesses or automotive or power cables, a larger-diameter set around 15 mm offers quicker insulation for bigger wires, while still delivering dependable shrink performance and safety.
